“I’m too much of a fierce competitor, everyone knows if anyone beats me in something I want to get them straight back or sit there from dawn till dusk to beat them,” Mundine said.
“I didn’t want to hang them up on that note, you know what I mean?”
Parr, 43, has a 10-3 record with all of his wins coming by knockout but last stepped into the boxing ring 16 years ago as his attention switched to kickboxing.
Mundine said Parr would still be a dangerous opponent in November’s bout however.
“It’s been a while since he’s had a boxing fight but he’s in the stand-up game,” Mundine said.
“Muay Thai and kickboxing, you have to be handy with your hands nonetheless … it’s the art of fighting even if it’s not solely boxing.
“He’s going to be ready. I know that.”
